Barry,
I'm still trying to solve the lighting problem. My next step is to be certain that the TIU and remote are both loaded with DCS 5.0. I do not know how to determine the code version in the TIU. The remote screen says 5.0.
How do I know the version in the TIU? I have the latest version of your book, but I am unable find information pertaining to the TIU code version.
